Trapping molecular bromine: a one-dimensional bromobismuthate complex with Br2 as a linker†
Abstract
The reaction between solid (NMP)n{[BiBr4]}n (1) (NMP = N-methylpyridinium) and Br2, generated in situ in HBr solution, results in the formation of (NMP)3[Bi2Br9]·Br2 (2). In the structure of 2, dibromine molecules connect discrete binuclear [Bi2Br9]3− anions into an extended network. Complex 2 is thermally stable (up to 150 °C).
